# Latest Starlink & GPS TLEs

*Part of the [Orbital Mechanics Datasets](https://huggingface.co/collections/juliensimon/orbital-mechanics-datasets-69c24caca4ab3934c9856994) collection on Hugging Face.*


Latest Two-Line Element (TLE) orbital data for the **Starlink** (9,983 satellites) and
**GPS** (32 satellites) constellations, sourced daily from
[CelesTrak](https://celestrak.org/).

## Raw TLE files

For applications that consume standard 3-line TLE format (e.g., SGP4 propagators):

- [`data/starlink.tle`](https://huggingface.co/datasets/juliensimon/starlink-tle-latest/resolve/main/data/starlink.tle) — raw TLE text
- [`data/gps.tle`](https://huggingface.co/datasets/juliensimon/starlink-tle-latest/resolve/main/data/gps.tle) — raw TLE text

## Schema (Parquet)

| Column | Type | Description |
|--------|------|-------------|
| `name` | string | Satellite name (e.g., "STARLINK-1234", "NAVSTAR 78") |
| `line1` | string | TLE line 1 |
| `line2` | string | TLE line 2 |

## Usage

```python
from datasets import load_dataset

# Starlink TLEs
ds = load_dataset("juliensimon/starlink-tle-latest", "starlink", split="train")

# GPS TLEs
ds = load_dataset("juliensimon/starlink-tle-latest", "gps", split="train")

# Use with sgp4 library
from sgp4.api import Satrec
sat = Satrec.twoline2rv(ds[0]["line1"], ds[0]["line2"])
```

## Data source

[CelesTrak](https://celestrak.org/) (Dr. T.S. Kelso), mirroring NORAD/18th Space Defense Squadron data.
